Exhaust Gasket Set BBC w/Large Round Race Port

The Exhaust Gasket Set BBC w/Large Round Race Port from REMFLEX is a premium pair of exhaust header gaskets engineered for big block Chevy engines demanding maximum flow and reliability at high RPM. Whether you're building a street performance engine, a dedicated race platform, or restoring a classic muscle car, these graphite gaskets seal the critical junction between your headers and cylinder head where combustion pressure meets exhaust evacuation. Purpose-built for large round race ports, this gasket set eliminates leaks that rob horsepower and allow unburned fuel vapors to escape your engine bay.

Constructed from durable graphite material, the Exhaust Gasket Set BBC features a 2.40-inch round port design that matches modern high-flow race headers without compression loss or blow-by. Graphite construction provides superior heat resistance compared to conventional fiber gaskets, maintaining sealing integrity across extreme temperature cycles typical of race and modified engines. The pair configuration ensures you have gaskets for both driver and passenger sides, eliminating the need for separate purchases. These gaskets handle the thermal shock of exhaust pulses while resisting the caustic effects of unburned fuel and combustion byproducts that degrade inferior gasket materials over time.

BBC (big block Chevrolet) enthusiasts, bracket racers, and performance rebuilders trust REMFLEX gaskets for their reputation in high-output applications where factory gaskets simply cannot survive repeated heat cycles. Installation is straightforward—position the gaskets against the cylinder head ports, bolt your race headers to the block, and torque to manufacturer specification. Proper installation prevents exhaust manifold gasket failure that commonly occurs on modified big block engines running elevated boost, nitrous, or sustained high RPM power levels. For anyone serious about extracting every BTU from their BBC platform, these gaskets represent a critical reliability upgrade.
